Saturday Birthday Brunch - Downtown

I am planning a birthday brunch for approximately 18 people. It needs to be on a Saturday in June. I would like it to be downtown, either in the Village or Soho (I love the LES but I think grandparents, etc. will appreciate the Village/Soho more). I am having difficulties finding a place that will accomodate a large group - my ideals would be August or Blue Ribbon Bakery, but neither will accept parties of 18. Does anyone have any suggestions? Thanks very much.
